|It is a truism in the nozzle industry that while the choice of
atomizer is made in the final phase of a
process development/optimization project [often without much consideration], it is the first component to be blamed
when the process encounters difficulties.
Many industrial processes are critically dependent on the spray
performance of the atomizer.
drying, if the atomizer produces too large a maximum droplet diameter,
incompletely dried product will build up on the walls.
high-temperature quenching applications, even modest deviations in the
actual dropsize distribution produced by the atomizer can result in
excessive downstream temperatures and potential damage to bag house
components, scrubbers and precipitators.
liquid distribution within the spray envelope can result in poor mass- and
heat-transfer performance in a wide range of industrial processes, while variations in droplet velocities can
adversely affect residence time and coating efficiency.
spray research, inc. has the capabilities and expertise to objectively
evaluate a particular atomizer's performance and suitability for its
intended use. Situations that may indicate a need for an independent performance evaluation
of an atomizer include:
